Answer: $6.80

Step-by-step explanation:

We will represent the amount of money that Molly has with a m. So it tells us the relationship between Kevin's amount and Molly's amount. It is says Kevin has 2.20 less that 4 times Molly's amount so we could represent it by the equation.

25 = 4m -2.20 solve for m.

+2.20 +2.20

27.20 = 4m

m= 6.8

4(6.8) = 27.20 - 25 = 2.20

Find the distance between the points (3, 8) and (0,4).

Bingel [31]

Answer:

Step-by-step explanation:

(3,8) (0,4)

X1 = 3 X2 = 0

Y1 = 8 Y2 = 4

$D=\sqrt{(X1-X2)^{2}+ (Y1-Y2)^{2} }$

$D= \sqrt{(3-0)^{2} + (8-4)^{2} }$

Do what's in the parentheses so...

3-0= 3
8-4= 4

Now plug it in!

$D= \sqrt{(3)^{2}+(4)^{2} }$

Now you are going to finish the parentheses so...

(3)^2= 9
(4)^2= 16

Plug that in so that you have this...

$\sqrt{9+16}$

Add 9+16 to get...

$\sqrt{25}$

Then you are going to find the number or numbers that make this a perfect square...

$\sqrt{25}= 5$

So 5 is your answer

A collection of dimes and quarters has a total value of five dollars and contains 29 coins. How much of each kind of coin are th

hjlf

A quarter and a dime are equal to 25 cents and 10 cents, respectively. Let x and be the number of quarter and dime coins. The equations that best expressed the condition are,
x + y = 29
0.25x + 0.10y = 5

The values of x and y are equal to x = 14 and y = 15. Thus, the answer is letter A. 15 dimes and 14 quarters.
